Dean and Helena have ministered at events in the US and abroad, notably at the Christian celebration of the Feast of Tabernacles, Jerusalem, Israel. Their presentations incorporate banners, symbolic garments and objects used in interpretive movement and pageantry. They offer biblical teaching, illuminating the Jewish roots that bring depth to our faith in Jesus.

ZionFire has ministered in visual arts throughout the US and at conferences in Europe, Israel, Mexico, and Canada. Their banners have been featured in state capitols on both coasts for prayer and proclamation rallies. In 1994, they chose the name ZionFire and became an official ministry duo, based in western Pennsylvania. In 1995-96, they were part of a core group who started a new Foursquare church in Youngstown OH. Since coming to Kansas City in 1996, they have joined the Charismatic Episcopal Church, where Helena is a commissioned minister in the area of banners and pageantry. Dean currently serves the Cathedral as prayer coordinator.

ZionFire has provided pageantry for such large events as: Congress on the Holy Spirit and Evangelism in 1994, Orlando; Worship Life Conferences, Pittsburgh PA; Bless Pennsylvania Rally, Harrisburg PA and similar events in Sacramento CA and Olympia WA; Exaltation in Columbus, OH; One Nation, One King Conference in Tampa, FL; Taste of the Feast of Tabernacles events in Youngstown OH and Knoxville TN; six Marches for Jesus in five cities in two countries, two March for His Glory events in Mexico City, and Aglow International conventions. Recent events include A Night to Honor Israel with John Hagee in Miami, FL, and the 2008 ICCEC International Convocation in Orlando.
